虽然睡眠呼吸障碍（SDB）已被证明是非常普遍的老年人，很少有人做了检查不同种族群体的老年人之间的差异。有充分的证据表明，SDB经常导致高血压，并且高血压在非洲裔美国人中比在白人中更常见。因此，人们可能会怀疑SDB可能在非洲裔美国人中更常见。研究对象为65岁以上的高加索人（n = 346）和非洲裔美国人（n = 54）。非裔美国人对睡眠的满意度较低（p = 0.017），入睡困难（p < 0.001），白天嗜睡（p = 0.0014）和早晨头痛（p = 0.0043）。非裔美国人每晚小睡的频率比白人高0.8倍（p = 0.05），每次小睡的时间比白人长11分钟（p = 0.019），他们的总睡眠时间也有增加的趋势（428对408分钟）。更令人感兴趣的是，更多的非洲裔美国人患有严重的SDB，其相对风险是白人的两倍（相对风险= 2.13），这在logistic回归分析中得到证实，其中种族与SDB的存在（RDI大于或等于30）独立于年龄，性别和体重指数。患有严重SDB的非裔美国人的平均RDI显著高于白人（72.1 vs 43.3; p = 0.014）。
Although sleep-disordered breathing (SDB) has been shown to be very prevalent in the elderly, little has been done to examine differences between the elderly of different racial groups. It has been well documented that SDB often results in hypertension and that hypertension is more common in African-Americans than in Caucasians. Therefore, one might suspect that SDB might be more common in African-Americans. Caucasians (n = 346) and African-Americans (n = 54) older than 65 yr of age were studied. African-Americans reported less satisfaction with sleep (p = 0.017), more difficulty falling asleep (p < 0.001), more daytime sleepiness (p = 0.0014), and more frequent morning headaches (p = 0.0043). African-Americans napped 0.8 times more frequently per evening (p = 0.05) and 11 min longer per nap (p = 0.019) than did Caucasians, and they showed a trend toward more total sleep time (428 versus 408 min). Of greater interest was the fact that more African-Americans had severe SDB with a relative risk twofold as great (relative risk = 2.13) as that for Caucasians, which was confirmed in a logistic regression analysis where race was associated with the presence of SDB (RDI greater than or equal to 30) independently of age, sex, and body mass index. The mean RDI for those African-Americans with severe SDB was significantly higher than that for Caucasians (72.1 versus 43.3; p = 0.014).
